SVP David P Clement sold 2,212 VMC shares ($646.5K) at $292.29; holds 8,716 post-trade at current $300.83 (-9.1% from high).

David P Clement, Senior Vice President, sold 2,212 shares of Vulcan Materials for $646,545.48 on 2026-06-15, reducing his holdings by 20.2% to 8,716 shares. The sale occurred at $292.29 while the current price stands at $300.83, suggesting modest stock appreciation since the transaction. His same-ticker history at VMC shows 1 of 3 prior sells were well-timed at the 90-day mark, with the most recent pair in November 2025 generating modest positive 90-day returns (5.3% and 4.2%), while one earlier sale showed a 4.2% loss over 90 days. The stock trades 9.1% below its 52-week high but up 12.3% over the past 30 days and 16.7% over 90 days, reflecting recent strength despite elevated valuation metrics (P/E 35.06).

BAKER THOMPSON S II Sell
President
7,135 shares
$2,146,279
@ $300.81
Significance 6/10

President Baker Thompson S II fully exits 7,135 shares of VMC at $300.81, clearing all holdings in $2.1M transaction

Baker Thompson S II sold 7,135 shares representing 100% of his position at $300.81 on 2025-12-11, generating $2,146,279.35 in proceeds. The sale occurs near the stock's 52-week range of $220.90–$309.07, with VMC trading 4.0% from the 52-week high and up 5.7% over 30 days. Across his open-market history (12 prior sells on all tickers), Thompson achieved a 90-day well-timed rate of 100.00% with an average 90-day return of -10.0% post-sale, indicating a strong track record of selling before declines. At VMC specifically, his 5 prior trades show mixed outcomes, with the most measurable outcome (2024-05-13) returning -10.4% over 90 days. The complete liquidation of a president's holdings in a company with $2.3B quarterly revenue and positive net income of $374.9M warrants attention to whether this reflects a planned diversification event or signals changing conviction about the company's trajectory.

Clement David P Sell
Senior Vice President
2,000 shares
$577,100
@ $288.55
Significance 6/10

SVP Clement sells 2,000 shares at avg $288.55; reduces holdings -70.6% to 832 shares

Clement David P, SVP of Vulcan Materials, executed 2 separate sales totaling 2,000 shares for $577,100.00 on 2025-11-19, reducing his holdings from 2,832 shares to 832 shares—a -70.6% reduction. The sales occurred at prices of $287.10 and $290.00, near the current price of $287.19 and well above the 52-week low of $220.90. His cross-ticker track record shows a 100.00% well-timed rate on his 1 prior sell, with that specific trade at VMC (executed 2024-02-29) also well-timed at the 90-day mark. The magnitude of this reduction—eliminating roughly two-thirds of his position—combined with his historical pattern of well-timed sells, merits investor attention. Vulcan's fundamentals show revenue growth of -4.7% year-over-year and a P/E of 33.95, suggesting a stock valued on expectations rather than trailing earnings.

BAKER THOMPSON S II Sell
President
4,853 shares
$1,434,714
@ $295.63
Significance 6/10

VMC President Baker Thompson sells 4,853 shares ($1.4M) at $295.63 avg; stock down 8.1% in 30 days post-trade

Baker Thompson S II executed two separate sales on 2025-11-12, totaling 4,853 shares for $1,434,714.50 at a blended average price of $295.63, reducing his holdings by 10.5% from 46,338 to 41,485 shares. The timing is noteworthy: Thompson's prior three measurable sales at VMC all resulted in negative 90-day returns (ranging from -8.6% to -10.4%), reflecting a 100% well-timed rate at this ticker specifically. Since the sale on 2025-11-12, VMC has declined 8.1% over 30 days and 2.6% over 90 days, continuing a pattern where his exits have preceded weakness. Across his cross-ticker track record, Thompson's 10 prior open-market sells averaged -10.0% 90-day returns with a 100.00% well-timed rate, suggesting consistent execution discipline in recognizing inflection points ahead of broader declines.

HALL GRAYSON Sell
4,658 shares
$1,354,267
@ $290.74
Significance 6/10

Director Grayson completely exits 4,658 VMC shares via 2 sales on Nov 10 for $1,354,266.74; holds zero post-transaction.

Grayson sold 4,578 shares at $290.73 and 80 shares at $291.31 on 2025-11-10, a blended average price of $290.74, completely liquidating his entire 4,658-share holding. The transactions total $1,354,266.74 at a time when VMC trades at $295.09, only 4.5% below its 52-week high of $309.07. The complete exit of a director's position warrants investor attention: full liquidation of holdings is a more definitive signal than partial sales, and the timing occurs when the stock is near its year-high valuation range. Vulcan Materials operates a large balance sheet (market cap $39.0B, $2.3B quarterly revenue) with modest profitability ($374.9M net income), and recent fundamentals show -4.7% annual revenue growth and a stretched P/E of 34.88, providing context for evaluating the significance of insider confidence levels reflected in this filing.

BAKER THOMPSON S II Sell
President
4,243 shares
$1,229,452
@ $289.76
Significance 4/10

President Baker Thompson S II sold 4,243 shares of VMC at $289.76 on 2025-11-10; retains 41,485 shares post-sale.

President Baker Thompson S II sold 4,243 shares at $289.76, reducing his holdings by 9.3% to 41,485 shares. His cross-ticker track record shows 11 prior sells with a 90-day well-timed rate of 100.00%, suggesting consistent historical accuracy in sale timing; however, his prior trades specifically at VMC showed 2 of 2 prior measurable sales (on 2024-05-13) with negative 90-day returns of -10.4%, aligning with favorable timing. The current stock price of $295.09 is -4.5% from the 52-week high of $309.07, positioning this sale near recent highs. VMC's valuation remains elevated at a P/E of 34.88 with annual revenue contraction of -4.7%, creating a backdrop where insider dispositions warrant monitoring against near-term price momentum.

Bass Stanley G Sell
Chief Strategy Officer
3,333 shares
$959,904
@ $288.00
Significance 5/10

Chief Strategy Officer Bass Stanley G sold 3,333 shares of VMC at $288.00 for $959,904.00

Bass Stanley G, Chief Strategy Officer, sold 3,333 shares at $288.00 on 2025-11-07, reducing his holdings from 31.0K to 27.6K shares (a 10.8% reduction). The sale occurred at a price 4.5% below the 52-week high of $309.07 and represents the fourth open-market sale at this ticker. Across his prior three sales at VMC, the insider has had no well-timed outcomes at the 90-day mark (all three resulted in subsequent gains: 3.6%, 2.0%, and 4.2%), indicating poor timing on similar sales. With VMC trading at a P/E of 34.88 and showing -4.7% annual revenue growth against a $39.0B market cap, the stock's valuation backdrop differs materially from the outsized multiples of recent years, though current near-term price momentum remains relatively stable at -2.5% over 30 days.

BAKER THOMPSON S II Sell
President
5,818 shares

@ $292.26
Significance 7/10

Baker Thompson S II (President) sold 5,818 shares of VMC at $292.26, liquidating entire position for $1.7M

President Baker Thompson S II executed a complete liquidation of his 5,818-share VMC position at $292.26 on 2025-11-04, eliminating all holdings post-transaction. His cross-ticker track record shows 8 prior sells with an average 90-day return of -10.0% and a 100.00% well-timed rate, indicating his historical sells have consistently preceded stock declines. At VMC specifically, all 5 of his prior trades were well-timed at the 90-day mark, with 90-day returns ranging from -10.4% to -9.7%, establishing a strong pattern of timing acuity at this ticker. The current stock price of $286.30 is -7.4% from the 52-week high and has declined -4.8% over 30 days, positioning this sale within an active downtrend. The company's annual revenue growth stands at -4.7%, suggesting operational headwinds that align with his decision to fully exit.

Hill J Thomas Sell
Chairman & CEO
87,553 shares
$24,103,043
@ $275.30
Significance 8/10

VMC Chairman & CEO sells entire 87.6K share position for $24.1M across 8 transactions May 19–20

Chairman & CEO Hill J Thomas executed 8 separate sales on May 19–20, 2025, liquidating his complete holdings of 87,552 shares for $24,103,042.68 at a blended average price of $275.30. This represents a 100% exit from his equity position in Vulcan Materials. The stock currently trades at $270.54, within its 52-week range but -7.4% from the high of $292.31, and has gained 15.5% over the past 30 days. At the same ticker, his prior 5 trades show a mixed pattern: 3 of 5 prior sells were well-timed at the 90-day mark, though recent November and October 2024 sales underperformed or declined modestly. The full liquidation of a CEO's holdings is a material signal that typically merits investor scrutiny, particularly given the company's elevated P/E of 38.10 and annual revenue contraction of -4.7%, though the company maintains a $35.7B market cap and recent quarterly net income of $128.9M.

$795,000
@ $265.00
Significance 4/10

Vulcan Materials Chief Strategy Officer sells 3,000 shares at $265.00; retains 30,953 shares post-sale

Bass Stanley G, Chief Strategy Officer of Vulcan Materials, sold 3,000 shares at $265.00 on 2025-05-02, reducing his holdings by -8.8% to 30,953 shares and realizing $795,000.00 in proceeds. The sale occurred when VMC stock was trading 8.6% below its 52-week high of $292.31. His prior sells at VMC (2 trades on 2024-02-22 and 2024-02-21) showed a TIMING PATTERN of 0 of 2 prior sells well-timed at the 90-day mark, with respective 90d returns of +2.0% and +4.2%—meaning the stock rose after both prior sales. This sale does not represent a shift in conviction; the CSO maintains a significant position of 30,953 shares post-transaction. VMC fundamentals show annual revenue growth of -4.7% and a P/E of 37.64, while the 30-day post-filing price movement was +15.8%.
